For an accessible and comprehensive survey of telecommunications and data communications technologies and services, consult the Telecommunications and Data Communications Handbook , which includes information on origins, evolution and meaningful contemporary applications. Find discussions of technologies set in context, with details on fiber optics, cellular radio, digital carrier systems, TCP/IP, and the Internet. Explore topics like Voice over Internet Protocol (VoIP); 802.16 & WiMAX; Passive Optical Network (PON); 802.11g & Multiple Input Multiple Output (MIMO) in this easily accessible guide without the burden of technical jargon.
When you open this page we ask eCampus, Knetbooks, BiggerBooks and VitalSource for their current prices on ISBN 9780470396070 and sort every offer by its total with shipping. Rental rows show the term (semester, quarter or short term) and that term goes with you to the store's cart, and eBook rows link straight to the 180-day or no-expiry option you picked. Prices are rechecked at least every 30 minutes, so confirm the total at checkout.
